Title: Developing device
Inventor: NAKAMURA TADASHI
IPC: G03G15/08
Filed: 1982-08-31
Abstract: PURPOSE:To obtain a developing device which never stains recording paper even if toner sticks to the reverse surface of the recording paper, by making the width of a guide roll provided on the rear side of the recording paper less than the width of the recording paper. CONSTITUTION:The width of the roll 5 for guiding the recording paper is less than the width of the recording paper 6. Then, even when the width of a toner layer 3a conveyed by rotation is greater than that of the recording paper 6 and toner moves around the paper 6 to its reverse surface, the toner falls naturally when magnetic attracting force operating on the toner decreases as the paper 6 leaves a rotating magnet 1 because there is a gap between the paper 6 and roll 5. Therefore, the reverse surface of the recording paper is not stained.

Title: Reproducing method of magnetic recording signal
Inventor: SAWADA TAKESHI
IPC: G11B5/02
Filed: 1980-10-29
Abstract: PURPOSE:To make a device small-sized, by detecting a variation of amplitude or frequency by a signal magnetic field by use of a magnetic reluctance effect type magnetic head whose detecting current is AC, and reducing a decrease of a reproducing output, in a domestic VTR device, etc. CONSTITUTION:An MR head 20 constituted by use of a magnetic reluctance effect element is connected to one side of an AC bridge circuit 22 to which an AC signal of an AC oscillator 23 is applied, through a rotary transformer 21. To a part of the circut 22, an element 25 constituted of an inductance and a resistance for balancing the bridge is installed. Oscillation frequency of the circuit 23 is selected to about 12MHz since frequency of a magnetic field applied to the head 20 is 2-6MHz. According to such a constitution, a variation of a magnetic field applied to an element of the head 20 executes an amplitude modulation as a variation of AC impedance, and a reproducing signal with fidelity according to a recording signal is outputted from an amplifier 24. Since the amplitude or the frequency modulation is detected in this way, a decrease of a reproducing output is reduced, and a device is small-sized.
